In mobile ad-hoc networks Quality of Service (QoS) of a multicast routing protocol is one of the most key performance metrics. Slotconditions and network topology frequently change (Topology dynamic), and in order to achieve a certain level of QoS, complexalgorithms and protocols are needed. Network graph conditionsare neglected during the design of aexisting multicast protocol. However, vulnerability against network graph errors can severely affect theperformance of a multicast protocol. To address this here the author proposesanenergy efficient network graph pre-processing approach to enable traffic engineering and enhance the performance of energy efficiency in terms of network efficiency by QoSprovisioning, to cater the multicast routing issue in MANETS.In this approach prioritized admission control (PAC) scheme is implemented to improvise D2D (Device to Device) communications into cellular network to overcome the limitations of MANETs.
